Jaymie Adams, who authorities said was 7 weeks pregnant, was found dead along a dirt trail in December 2011 with apparent stab wounds and blunt force trauma to her head. Investigators said Justin Adams willingly handed over his laptop, which included seven email accounts that linked his wife to online prostitution.

Justin Adams was formally charged with murder in February 2012. However, in April 2013, those charges were changed when police arrested Joseph Cyr after a DNA test showed Cyr had sex with Jaymie Adams the night before she disappeared.

Justin Adams' charges were then reduced to manslaughter.
